Police in St. Cloud said on Sunday that there's no evidence at this stage that the attack is linked to what happened in New York.

The Washington Post reports that nobody was seriously injured in the blast, which was caused by the detonation of an improvised explosive device.

The New York Post reports that early on Monday, the FBI launched a raid in Rahami's hometown of Elizabeth, hours after discovering five suspicious devices in the region – one of which blew up near a train station.

Although he initially said that there is no evidence linking the explosions to international terrorism, New York Gov. Andrew Cuomo has since admitted that may now be the case, telling CBS News: "I suspect there may be a foreign connection. That’s what we are hearing today, as the investigation goes on."
